Rick...lets take a step back. I think there is some confusion due to the wording of your original post.
You asked about how to wire an inverter to "solar prep". That would never happen...you could wire an inverter to the "Gen Prep" area. Do you have the "gen prep" package?
"Solar Prep" would be used to charge battery bank, it has nothing to do with A/C power, other than charging the battery bank, that is then used by an inverter.
